Changed the behaviour of the arg_check module so that the functions can return answers.

The raise_error flag is now accepted by all is_*() functions. If this is False, then the functions
will return either True or False, answering the question. This should allow the functions to be
used more extensively.

Fix for the arg_check.is_list call used in the fix at r16130.

This now will return the answer rather than raising a RelaxError.
